ADJUSTABLE CAN-OPENING MACHINE.

Application filed October The present invention relates toa can opening machineand has for its prime object to provide a structure which is adJuStable for opening different size cans.

Another important object of the invention is to provide a can opening machine of this ing a can and cutting means for severing the top of the can, said severing means and said clamping structure being a justable so as to accommodate different size cans. Another important object of the invention is to provide a can opening machine of this nature which is exceedingly simple in its construction, compact, convenient and efficient in its operation, reliable, strong, durable, not likely to easily become out of order,'easily manipulated, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other ob.- jects in view as will appear as thedescription proceeds, the invention resides in certain novel features of construction, and in s, 1925. Serial m. 51,256.

screw 14. iercing-the column 7 and extending intot e groove 13. A bearing sleeve 15 is slidable in the column 7 and is provided with longitudinally extending ribs 16 for moving in the grooves 7, thereby splining the bearing sleeve to the cover. A gear housing 18 is formed on the upper end of the bearing sleeve 15 and has a removable cover plate 19. A bearing sleeve 20 extends from the housing 18 rectangularly to the bearing sleeve 15, and terminates in a gear housing 21, having a removable cover plate 22. A shaft 23 is journa-led in the sleeve 15 and has a square extension 24 at its lower end slidable through the hub 12 for rotation therewith. A beveled ear 25 is fixed to the 'hub 12 and meshes wit the-beveled gear 11.

Thus'the rotation of the hand wheel 10 will cause rotation of the shaft 23. A beveled gear 27 is fixed on the upper end of the shaft 23, and 'meshes with a beveled gear 28 on one end of a shaft 29 journaled in the sleeve 20. A beveled gear3Q is provided onthe other end of the shaft 29 and meshes with a 25 the combination and arrangement of parts bevel gear31 on a shaft-32journaled in the as will be hereinafter more fully described and claimed.

In the drawings :J Figure 1 is a vertical section of the device embodying the features of my device.

Figure 2 is a sectional elevation of the machine. T

figure 3 is a top plan view'of the machine, an

Figure 4 is a horizontal section taken sub- 7 on the inner end thereof. A hub 12 is pro- .vided withan annular groove 13. This hub 12 is journaled for rotation in the lower end of the column 7, and is held inplace'by 9. upon the height of the particular can being cutter 35 in a circular path. The diameter of this "circular path may be changed by the adjustment of the shank 34, depending, of

course, on the diameter of the particular can with which the pipe is being used. As is shown to advantage in Figure'2, the column 7 is provided with a vertically extending slot 38. The sleeve 15 is provided with. a longitudinally extending rack 39. A bracket 40 is provided on thecolumn 7, and pivotally mounts as at41 a lever 42 provided with the gear se ent 43. A'pinion 44is journaled on the racket 40 and meshes with the gear segment 43 and the racks 39 so that by swinging the lever 42 the sleeve 15 and parts mounted thereon may be raised or lowered.

" Thus the height of the cutter 35 may bechanged in re ation to the base 5 depending lever in different adjusted positions.

opened. Referring now particularly to the clamping mechanism for holding the can, while the cutter is in operation, it will be seen that 46 denotes a substantially rectangular frame mounted on the base 5 by means of legs 47 or in any other suitable manner. A plurality of bars 48 and 49 extend longitudinally of the frame in spaced relation to each other, the two bars 49 being centrally located, and the other bars being located adjacent the sides of the frame, a pair of arcuate clamp jaws 50 have sleeves 51 slidable on bars 49 and grooved lugs 52 slidable on bars 48. A lever 53 is pivoted at one end as at 54 on the center of a cross bar 55 supported on the frame 46. The pivoted end of the lever 43 is provided with a cross head 56. Ad justable links 57 are pivoted to the respective ends of the cross head 56 and to intermediate portions of the clamp jaws 50. These links are provided with a plurality of apertures for receiving the pivotal .connection between the links and the jaws so that adjustments may be made therebetween. A rack 58 is curved and mounted at one end of the frame 46 for being engaged by the free end of the lever 53 so as to hold saiId 1', will be seen that by swinging the lever 53, the jaws may be moved toward or away from each other for clamping tightly or releasing the jaws from the'can.

.From the above detailed description, it is thought that the construction, operation, and advantages of the invention will be clearly understood. The structure has numerous different adjustable features so that cans of practically all sizes .now in usermay be opened thereby.

The assemblage of the various parts recited possesses superior compactness and convenience without in anyway sacrificing simplicity The structure which I have-disclosed is merely given'by way of example because in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the details of construction, and

in the combination and arrangement of parts may be resorted to Without departing from the spirit'or scope of the invention as hereinafter claimed or sacrificing any of it's ad vantages.

Having thus described the invention,what

. I claim as new and desire to secure by Letters Patent is I -1. In a machine of the class described, a

base,-a casing rising from the base, a cylindrical hollow column rising from the casing and provided with vertical grooves, a hub rotatable in the bottom end of thecolumn, a bearing sleeve having a pairi'of-xribs, said sleeve beingjfslidable in the with the ribs in said f'grooves, means for raising and lowering the sleeve, a shaft journaled in the sleeve and having a square extension slidable through the hub to be rotated thereby, a second bearing sleeve rectangularly disposed at the upper end of the first sleeve, a second shaft journaled in the second sleeve, gearing between the shafts, a cutting mech- 'anismmounted at the end of the second sleeve, and means operatively connecting the second shaft and said cutting means.

2. In a machine of the class described, a base, a casing rising from the base, a cylindrical hollow column rising'from the casing, a hub rotatable in the bottom end of the column, means for rotating the hub, a bearingsleeve splined within the shaft, means for raising and lowering the sleeve, a shaft journaled in the sleeve, and having a square extension slidable through the hub to be rotated thereby,-a second bearing sleeve rectangularly disposed at the upper end of the first sleeve, a second shaft journaled to the second sleeve, gearing between the shafts, a housing on the end of the second sleeve,'a shaft in the housing, gearing between the second and third shafts, said third shaft terminating in a sleeve, a shank adjustable in said sleeve, means for holding the shank in different adjusted positions, and a cutter on one end of said shank.

3. In a machine of the class described, a
